[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0027] Please see Figure 1-5 In this utility model: a test platform for easily adjustable multi-layer composite microcrystalline sound insulation materials includes a soundproof box 1. A sliding rod 2 is fixedly connected to the inner wall of the soundproof box 1. Two sound insulation plates 3 are slidably connected to the sliding rod 2. The outer sides of both sound insulation plates 3 are slidably connected to the inner wall of the soundproof box 1. A lead screw 4 is rotatably connected to the inner wall of the soundproof box 1. The top end of the lead screw 4 passes through and extends to the top of the soundproof box 1. Both sound insulation plates 3 are fitted onto the lead screw 4 and threadedly connected to it. Each of the two sound insulation plates 3 has a test port 5. [The last sentence appears to be incomplete and possibly refers to a different product: sound insulation...] A speaker 6 is installed on the inner top wall of the soundproof box 1, and a microphone 7 is installed on the inner bottom wall of the soundproof box 1. A test system 8 is set on the right side of the soundproof box 1. The test system 8 includes a central processing unit 801, which is installed on the left side of the soundproof box 1 on the right side. The central processing unit 801 is bidirectionally connected to a data analysis module 802, a data acquisition module 803, and a signal generator 804. The output of the signal generator 804 is connected to the speaker 6, and the output of the data acquisition module 803 is connected to the microphone 7.

[0028] In this invention, when testing the multi-layer composite microcrystalline sound insulation material, the soundproof box 1 is first opened. Then, the distance between the two soundproof panels 3 is adjusted according to the thickness of the material. The user can rotate the screw 4 to drive the two soundproof panels 3 to move relative to or opposite to each other along the slide bar 2. After adjusting the distance between the soundproof panels 3 to be greater than the thickness of the multi-layer composite microcrystalline sound insulation material, the user can insert the material between the two soundproof panels 3, and then move the material to align the center of the material with the detection port 5. Next, the screw 4 is rotated to drive the two soundproof panels 3 to move towards each other until the two soundproof panels 3 are in close contact with the material, thus completing the fixation of the material. At this time, the center of the material will be in the detection port 5. Then the user closes the soundproof box 1, at which point the soundproof box 1 will be... The sound insulation panel 3 and the multi-layer composite microcrystalline sound insulation material are divided into two parts. The sound at the top of the sound insulation box 1 needs to pass through the multi-layer composite microcrystalline sound insulation material to reach the bottom of the sound insulation box 1. At this time, the preparation work before testing the multi-layer composite microcrystalline sound insulation material is completed. During monitoring, the central processing unit 801 first controls the signal generator 804 to drive the speaker 6 to emit a sound signal with a specific frequency, intensity and waveform. Then, the microphone 7 at the bottom of the sound insulation box 1 will receive the sound signal after being sound-insulated by the test material. The data acquisition module 803 will collect the signals from the microphone 7 and the speaker 6 to realize data acquisition. The data analysis module 802 will analyze the acquired data to obtain the sound insulation effect of the material and complete the test of the sound insulation effect of the material.

[0029] The user can adjust the distance between the two sound insulation plates 3 by rotating the screw 4, thus making it suitable for testing multi-layer composite microcrystalline sound insulation materials of different thicknesses. Moreover, when testing multi-layer composite microcrystalline sound insulation materials of different sizes or shapes, only the portion with the test port 5 is tested, thus making it suitable for testing multi-layer composite microcrystalline sound insulation materials of different sizes.

[0030] Please see Figure 1 and 2 The soundproof box 1 has a touch screen 9 installed on its front side, and the touch screen 9 is bidirectionally connected to the central processing unit 801.

[0031] In this invention, the touchscreen 9 facilitates the display of test data by the user, thereby improving the practicality of the device.

[0032] Please see Figure 1-4 The top of the soundproof box 1 is threaded with a screw 10, and the bottom end of the screw 10 is fixedly connected to a mounting plate 11. The top of the speaker 6 is mounted on the mounting plate 11.

[0033] In this invention, the user can rotate the screw 10 to raise and lower the mounting plate 11, thereby controlling the height of the speaker 6 and achieving the effect of controlling the distance between the speaker 6 and the sound insulation material. This allows for the adjustment of the test environment, simulating different actual usage scenarios and effectively improving the test results.

[0034] Please see Figure 1-4 The top of both the screw 10 and the lead screw 4 are fixedly connected to a handle 12, and a sealing ring 13 is fixedly connected to one side of the sound insulation plate 3.

[0035] In this invention, the handle 12 allows the user to easily rotate the screw 10 and lead screw 4, thereby improving the practicality of the device. The sealing ring 13 can improve the sealing effect between the sound insulation plate 3 and the test material, prevent sound leakage, and improve the quality of the test.

[0036] Please see Figure 4 Among them, a sealing ring 14 is embedded on the sound insulation panel 3, and the outer side of the sealing ring 14 is in contact with the inner wall of the sound insulation box 1.

[0037] In this invention, the sealing ring 14 can seal the sound insulation board 3 and the sound insulation box 1, preventing sound leakage and improving the quality of the test.

[0038] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
